Abstract

The use of underground coal gasification process for the recovery of deep underground seams for the production of methane-rich gas is now becoming a topical issue again. The protection of water resources, which could be contaminated with organic or inorganic pollutants during the washing of emerging products, is closely related to this issue. The article brings data on the elution of organic as well inorganic pollutants from samples obtained after the UCG process performed in ex-situ unit.
